I am stuck with finding the right layout for visualizing trade costs. These are weighted directed flows signifying the cost of trade among countries. The higher the value, the higher the cost of trade and the lower the value the lower the cost of trade. What would be nice to see is for example country's which are geographically distant but have lower trade costs are seen closer together.

Thanks so much for this, I have played around with the MDS plugin and I seem to be in the right direction. I just can't quite understand the benefit of the different dimensions. If I run the tool under 4 dimensions lets say, what is recommended for the visualization part, for example 1st and 4th dimensions? I would really appreciate if you can help me understand this better. Thank you so much for your kind advice
